Abstract

A new layered perovskite compound, KLaTa₂O₇, was synthesized by ion-exchange reaction from the rubidium compound, RbLaTa₂O₇. The crystal structure of KLaTa₂O₇ was determined by Rietveld analysis from powder X-ray diffraction patterns. It is analogous to the structure of the corresponding niobate compound. This layered perovskite compound is a new member of the Dion-Jacobson series with n = 2 for the general formula A[M_{n -1}B_nO3_{n + 1}] (A = monovalent cations, B = Nb or Ta). The structural features of KLaTa₂O₇ are discussed by comparison with other compounds of the ALaTa₂O₇ family and the titanate compounds.
